Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same parts are assigned the same number, and duplicate explanations are omitted. In addition, it should be noted that the drawings may be exaggerated in order to understand the present invention and are not necessarily expressed in detail according to the scale. The present invention is not limited to the examples shown below.

Prior to explaining the examples, the gist of the present invention will be described. The present inventor has proposed a water treatment method (International Publication No. WO / 2015/145563) for refining clusters of water molecules. In this water treatment method, a cavitation generation ring in which a plurality of protrusions are projected from the inner peripheral surface of the cylindrical portion toward the center so as to form a water flow passage inside the cylindrical portion is used for the flowing water pipe. It is a water treatment method that is installed in a part of the cylinder and allows water to pass through the cylinder at high pressure to cause cavitation in the cylinder and refine the clusters of water molecules. In this water treatment method and water treatment device, a magnetic field is applied to the conductive vacuum microbubbles generated by cavitation to generate a force based on Fleming's left-hand rule, and the force is used around the vacuum microbubbles. It is a miniaturization of the cluster of water molecules. When the fluid collides with a protrusion in the piping pipe, the pressure of the fluid around the collided part momentarily drops, causing the fluid to boil or the dissolved gas to be released, which causes the fluid to boil. Based on the fact that many small bubbles (vacuum microbubbles) are known to be generated.
As an application of the water treatment method, when a ring similar to the cavitation generation ring was placed in the piping pipe and the experiment of circulating a fluid such as water with a pressure pump was repeated, it was discovered that the piping pipe became hot.
The present inventor has come up with the structure of the present invention in which the fluid can be self-heated when a ceramic body is used as the material of the ring while repeating the invention, trial manufacture, and experiment of various rings. That is, it is considered that the energy motion of the fluid itself has led to self-heating regardless of the properties of the gas or liquid. That is, in the process of cavitation of the fluid, under certain conditions, the fluid flowing at high pressure collides with the protrusions of the ceramic body and causes friction, which causes far infrared rays to be generated to draw out the self-heating of the fluid. As a result, it is thought that the piping pipe through which the fluid flows is heated.

The first embodiment will be described in detail with reference to the drawings. 1A and 1B are views showing the structure of the turbulence generation ring 1 according to the present invention, where FIG. 1A is a schematic front view and FIG. 1B is a schematic vertical sectional view taken along the line XX of FIG. 1A.

See FIGS. 1 (a) and 1 (b). The turbulent flow generation ring 1 according to the present invention has a plurality of protrusions 11a, 11b, 11c, from the inner peripheral surface 10 of the cylinder toward the center so as to form a flow passage 13 of the fluid L inside the cylinder. 12a, 12b, and 12c are projected. In the first embodiment, the turbulent flow generation ring 1 has a plurality of protrusions 11 (11a, 11b, 11c in the figure) and a plurality of protrusions 12 (12a, 12b in the figure) having substantially the same size and shape. 12c), the protrusions 11 and 12 have a mushroom shape including mandrel 110, 120 and heads 111, 121, and the dimensions of the heads 111, 121 are at least two or more combinations.
As will be described later, the protruding dimension of the protruding portion 11 is larger than that of the protruding portion 12, but the protrusion size is not particularly limited.

See FIG. FIG. 2A is a schematic perspective view showing the mushroom-shaped member 11 of the turbulent flow generation ring according to the present invention. FIG. 2B is a schematic perspective view showing the mushroom-shaped member 12 of the turbulent flow generation ring according to the present invention.
As shown in FIG. 2A, the protrusion 11 has a mushroom shape including a mandrel 110 and a head 111. As shown in FIG. 2B, the protrusion 12 has a mushroom shape including a mandrel 120 and a head 121. The protrusions 11 and 12 have two or more combinations of the heights of the mandrel 110 and 120 and the dimensions of the heads 111 and 121. In FIGS. 1 and 2, the shapes of the heads 111 and 121 are substantially disk-shaped, and the two types of heads 111 and 121 and the protrusions 11 and 12 having the mandrel 110 having a height higher than that of the mandrel 120 are exemplified. There is. By combining two or more types of protrusions 11 and 12 in this way, the above-mentioned shock wave can be efficiently generated. Further, by making the heads 111 and 121 substantially disk-shaped, turbulence can be generated in the fluid L flowing in the piping pipe.
The size of the protrusions 11 and 12 may be set so that the protrusions 11 and 12 do not interfere with each other. Further, the sizes of the heads 111 and 121 are shown by way of example and are not limited, and different shapes and dimensions such as three types and four types can be used as long as the protrusions do not interfere with each other.

See FIG. FIG. 3 is a cross-sectional view showing a state in which the flow velocity amplification ring 2 and the turbulence generation ring 1 are combined. In this combination, the flow velocity amplification ring 2 is arranged on the upstream side, and the turbulence generation ring 1 is arranged adjacent to the downstream side.

See FIG. 4A and 4B are views showing the structure of the flow velocity amplification ring 2, where FIG. 4A is a schematic front view, FIG. 4B is a schematic rear view, and FIG. 4C is a schematic vertical sectional view taken along the line YY. Referring to FIG. 4 (c), in the flow velocity amplification ring 2, the inner peripheral surface 20 of the cylinder is tapered from the inlet opening 21 toward the outlet opening 22, and this is a flow passage of the fluid L inside the cylinder. 23 is formed. As shown in FIG. 4A, in the first embodiment, a peripheral groove 24 is formed between the inlet opening 21 on the front surface of the flow velocity amplification ring 2 and the outer peripheral end of the cylinder, but it is not always necessary. As shown in FIG. 4B, a plurality of small recesses 250 are formed in the back surface 25 between the outlet opening 22 of the flow velocity amplification ring 2 and the outer peripheral end of the cylinder. As will be described later, in the plurality of small recesses 250, the accelerated fluid L enters the inlet opening of the turbulent flow generation ring 1 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the protrusions 11 and 12. When the shock wave returns to the outlet opening 22 of the flow velocity amplification ring 2, it has a role of diffusely reflecting the shock wave.

A configuration in which the flow velocity amplification ring 2 and the turbulence generation ring 1 shown in FIG. 3 are combined will be described. When the fluid L is passed through the flow velocity amplification ring 2 and the turbulence generation ring 1 at high pressure by a pressure pump, the fluid L first enters the cylinder of the flow velocity amplification ring 2 from the inlet opening 21 toward the outlet opening 22. In the process of traveling through the tapered flow passage 23, the flow velocity is amplified. The accelerated fluid L enters the inlet opening of the turbulent flow generation ring 1 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the protrusions 11 and 12. Then, the pressure of the fluid around the collision site is momentarily reduced. When the pressure of the fluid is lowered for a very short time, the fluid L boils or the dissolved gas is liberated by using the minute bubble nuclei of 100 μm or less existing in the fluid L as nuclei, which causes small bubbles (vacuum). It is known that a large number of microbubbles) are generated. Since the pressure of the fluid L around these vacuum microphone bubbles is higher than the saturated water vapor pressure, the inundated fluid L floods toward the center of the vacuum microbubbles, and at the moment when the vacuum microbubbles disappear, the flooded fluid L It collides at the center, which causes a strong shock wave.

Then, as described above, in the process of cavitationizing the fluid L, the fluid L flowing at high pressure collides with the protrusions 11 and 12 of the ceramic body of the turbulent flow generation ring 1, or causes friction on a part of the protrusions 11 and 12. When it is generated, far infrared rays are generated. It is thought that this far infrared ray draws out the self-heating of the fluid, which in turn heats the piping pipe through which the fluid flows.

The material used for the slow flow velocity ring 1 according to the present invention is a non-oxide ceramic body such as silicon nitride, sialon, silicon carbide, or boron nitride made of porous material, and a single material of zirconia, alumina, and mulite made of porous material. , Or a composite material of non-oxide ceramic bodies such as boron nitride and silicon nitride, or a composite material of a non-oxide ceramic body such as boron nitride and an oxide ceramic body such as zirconia, alumina, and murite. Is suitable. These ceramic bodies are particularly excellent in heat resistance, corrosion resistance, and heat impact resistance at high temperatures.
Further, the flow velocity amplification ring 2 may be made of a metal such as stainless steel, a synthetic resin, or the like, in addition to the above-mentioned material such as a ceramic body.
If the material used is a ceramic body, when the fluid L flowing in the piping pipe collides with the projection of the ceramic body, the far infrared rays emitted from the ceramic body due to the impact heat the temperature of the flowing fluid L. It is considered to work.

Further, the inner diameter of the cylinder of the flow velocity amplification ring 2 and the turbulence generation ring 1 according to the present invention may be, for example, 10 to 50 mm, and the width dimension of the cylinder (dimension along the flow direction of the fluid L) is, for example, 5. It may be up to 30 mm. Further, the protruding dimensions of the protrusions 11 and 12 of the turbulent flow generation ring 1 may be such that the protrusions 11 and 12 do not interfere with each other. For example, the protrusions are about 1/10 to 1/2 of the inner diameter of the cylinder. May be.

The second embodiment will be described in detail with reference to the drawings.

See FIG. FIG. 5 is a cross-sectional view showing a state in which the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulent flow generation ring 1 are combined. In this combination, the flow velocity amplification ring 2 is arranged on the upstream side, and the flow velocity slowing ring 3 is sandwiched between the turbulent flow generation ring 1 and the flow velocity amplification ring 2 on the downstream side. Hereinafter, the description of the flow velocity amplification ring 2 and the turbulence generation ring 1 according to the second embodiment is the same as that of the first embodiment, and the description overlapping with the first embodiment will be omitted in the second embodiment.

6A and 6B are views showing the structure of the slow flow velocity ring 3, where FIG. 6A is a schematic front view and FIG. 6B is a schematic vertical sectional view taken along the line ZZ of FIG. 6A.
The flow velocity slow ring 3 is provided with a fixed wing 31 having a plurality of wing portions 31a, 31b, 31c in the cylinder so as to form a flow passage 33 of the fluid L inside the cylinder, and each wing of the fixed wing 31 is provided. The portions 31a, 31b and 31c are positioned in the flow of the fluid L. That is, the fixed wing 31 has a plurality of wing portions 31a, 31b, 31c radially provided between the cylindrical inner core portion 35 provided inside the cylinder and the inner peripheral surface 30 of the cylinder and the inner core portion 35. It is composed of and. The fluid L flows through the flow passage 33 through the gaps between the plurality of blade portions 31a, 31b, 31c and the inner core portion 35 radially provided between the inner peripheral surface 30 of the cylinder and the inner core portion 35.

A configuration in which the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulent flow generation ring 1 shown in FIG. 5 are combined will be described. When the fluid L is passed through the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulence generation ring 1 at high pressure by a pressure pump, the fluid L first enters the cylinder of the flow velocity amplification ring 2 and exits from the inlet opening 21. The flow velocity is amplified in the process of advancing the tapered flow passage 23 toward the opening 22. The accelerated fluid L enters the inlet opening of the slow flow velocity ring 3 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the front surface 350 of the inner core portion 35, where a strong shock wave is generated. That is, the fluid L circulated at high pressure collides with the front surface 350 of the inner core portion 35 of the ceramic body of the slow flow velocity ring 3, and far infrared rays are generated. It is thought that this far infrared ray draws out the self-heating of the fluid, which in turn heats the piping pipe through which the fluid flows.
When the fluid L circulated at high pressure collides with the front surface 350 of the inner core portion 35 of the ceramic body of the slow flow velocity ring 3, the fluid L is diffusely reflected in a plurality of small recesses 350 formed in the front surface 350. Then, when the shock wave returns to the outlet opening 22 of the flow velocity amplification ring 2, the diffusely reflected fluid L further diffusely reflects the shock wave in the plurality of small recesses 250. The diffusely reflected liquid L flows through the flow passage 33 through the gap between the plurality of blade portions 31a, 31b, 31c and the inner core portion 35 while colliding with the plurality of blade portions 31a, 31b, 31c of the fixed blade 31, and the flow velocity slow ring. It flows from the outlet opening of 3 into the inlet opening of the turbulent flow generation ring 1.
After that, the fluid L generates a turbulent flow through the protrusions 11 and 12 arranged in the cylinder of the turbulent flow generation ring 1, and flows out from the outlet opening.
By combining the flow velocity amplification ring 2, the slow flow velocity ring 3, and the turbulent flow generation ring 1 of the second embodiment, the flow of the fluid L can be changed from the flow velocity amplification to the slow flow velocity, and the flow itself can be turbulent. , It seems that it leads to increase the entropy of kinetic energy.

The material used for the slow flow velocity ring 3 according to the present invention is a non-oxide ceramic body such as silicon nitride, sialon, silicon carbide, or boron nitride made of porous material, and a single material of zirconia, alumina, and mulite made of porous material. , Or a composite material of non-oxide ceramic bodies such as boron nitride and silicon nitride, or a composite material of a non-oxide ceramic body such as boron nitride and an oxide ceramic body such as zirconia, alumina, and murite. Is suitable. These ceramic bodies are particularly excellent in heat resistance, corrosion resistance, and heat impact resistance at high temperatures. When the material used is a ceramic body, it is considered that the temperature of the fluid L through which the far infrared rays radiated from the ceramic body when an impact is applied can be heated.

Further, the inner diameter of the cylinder of the flow velocity slow ring 3 according to the present invention may be, for example, 10 to 50 mm, as in the flow velocity amplification ring 2 and the turbulence generation ring 1 of the first embodiment, and the width dimension of the cylinder (fluid L). The size along the flow direction of the above) may be, for example, 5 to 30 mm.

The third embodiment will be described in detail with reference to the drawings.

As shown in FIG. 7, the fluid heating device 100 of the above combination is installed in a part of the piping pipe P, the fluid L is passed through the cylinder, and the fluid L is the inner core portion 35 of the ceramic body of the slow flow velocity ring 3. Far infrared rays are generated by colliding with the front surface 350, and further, the fluid L generates turbulence through protrusions 11 and 12 arranged in the cylinder of the first turbulence generation ring 1, and flows out from the outlet opening. Further, a turbulent flow is generated through the protrusions arranged in the cylinder of the second turbulent flow generation ring 1, and the turbulent flow is amplified by passing through the plurality of turbulent flow generation rings 1.

The piping pipe P may be configured to withstand the flow of a high-pressure fluid L, and may be made of a metal such as iron or copper or a synthetic resin such as polyvinyl chloride, for example. Etc. may be used. Further, the pressure of the fluid L passing through the flow velocity amplification ring 2, the flow velocity slow ring 3, and the turbulence generation ring 1 may be about 1 to 10 MP, and the flow velocity of the fluid L should be 150 m / min or more. Just do it. The pressure and the flow velocity of the fluid L may be appropriately adjusted in order to generate a shock wave effective for heating the fluid L, and may be adjusted according to, for example, the temperature of the fluid L. ..
